Photographs of colonies of (top) E. coli and (bottom) S. aureus (a, c) without nanoparticles treatment and (b, d) treated with SiO₂-Ag/PRh nanoparticles. Inset figures show the FE-SEM images of a single bacterial cell (left) in the absence of bactericidal agents and (right) treated with the as-prepared nanoparticles.
